Yoder A, Berezowitz C, Hanna E, Schoeller D. Farm to School Activity Tracker as an Accurate and Reliable Measure of Farm to School Programming. J Hunger Environ Nutr 2017;12(4):481-494.


The Farm to School Activity Tracker (F2SAT) allows diverse farm to school (F2S) programs to use a consistent tool for recording and tracking-related activities. Divided into 4 domains—school meals, classroom education, engagement activities, and gardening activities—the F2SAT is an accurate and reliable tool for cross-comparison of F2S program activities. Testing of the F2SAT occurred in 2 phases. The first stage tested accuracy using rankings by expert F2S mangers. The second stage tested interrater reliability as 5 assessors used the tool to measure the same F2S activities. This testing concluded that the F2SAT provides both a common language and form of measurement for practitioners and researchers. Further development of the F2SAT requires a broader pool of practitioners and researchers using the tool and reporting on how accurately and reliably it tracks their F2S activities.

Information about Development of Measure

Farm to School Activity Tracker (F2SAT) was developed as a means for F2S programs to record, monitor, and evaluate the activities comprising their programs. The F2SAT was designed by evaluators of F2S programs and by a nonprofit gardening/education specialist with experience implementing F2S programming. Feedback from state and regional F2S leaders helped to refine the tool's simplicity and ease of use.

Data Collection/Protocol

Activity data were collected in two stages, and included schools (grades three through five) participating in the Wisconsin Farm to School Evaluation. Stage one was during the 2010–2011 academic year and stage two occurred from September through November 2013. In the first stage, data were collected via an online questionnaire and electronically submitted school lunch information from Wisconsin AmeriCorps F2S members and health department staff who worked directly with schools implementing F2S programs. In the second stage, data were collected via a combination of an online questionnaire and supplemental electronic documents.
